fix(CA): fixing the topup amount and status check

[geekbrother]

Description

This PR fixes the following issues in the Chain Orchestrator:

• Calculating the exact topup amount (current destination chain balance - expected transfer amount) instead of just using the transfer amount, in this case, the remaining balance will be used for the transfer;
• Fixing the status check endpoint by adding the right (destination) contract and chain ID instead of the bridging data;
• Checking the ERC20 token destination balance amount to skip bridging if it's sufficient.

How Has This Been Tested?

• Integration tests for the chain orchestration were updated to catch this case.

Due Diligence

• Breaking change
• Requires a documentation update
• Requires a e2e/integration test update
